windows module lua5.1 Compilation fails about mlua HOT 6 CLOSED

A first example is from github actions where I test Lua modules on Windows:
https://github.com/khvzak/mlua/blob/master/.github/workflows/main.yml#L186

A second example is using Windows + MSVC

1. Download binary Lua dll & lib (I used the luabinaries project, this file)
2. Unzip to lua51 folder
3. Go to mlua/examples/module
4. From git shell

$ LUA_INC=$HOME/Downloads/lua51/include LUA_LIB=$HOME/Downloads/lua51 LUA_LIB_NAME=lua5.1 cargo build --features lua51

Build ok, we got mlua/target/debug/rust_module.dll

For testing:

1. Go to mlua/target/debug
2. Run

$ lua5.1 -e 'print(require("rust_module").sum(2,3))'
5
$ lua5.1 -e 'print(require("rust_module").used_memory())'

Windows 10, Latest MSVC Community, Git, Rust 1.49.0

from mlua.

Thank you very much for your reply. I succeeded !!!
The reason for the failure is that Lua's lib was downloaded incorrectly. I succeeded in both Lua5.1 and Lua5.4

from mlua.

Now I have a new problem. The compiled DLL is required and executed correctly by Lua54.exe, but not by LuaQuire in Rust. Any solution,
like this
`use mlua::prelude::*;

fn main() -> LuaResult<()> {
let lua = unsafe {Lua::new()};
lua.load(r#"print(require("my_module").sum(2,3))"#).exec()?;

Ok(())

}`

from mlua.

The line
let lua = unsafe {Lua::new()};
should be replaced with
let lua = unsafe { Lua::unsafe_new() };
to allow loading C modules

from mlua.

DLL is compiled in features=['lua54','module'] mode
The rust project is compliated with eatures=['lua54','vendored'] mode

from mlua.

Lua library does not load properly without lua54. DLL, but I cannot find a way to link lua54. DLL to the library

from mlua.
